CTI
Manager
3 The CTI Manager contains the CTI components
that interface with applications. With CTI
Manager, applications can access resources and
functionality of all Cisco Unified CallManagers in
the cluster and have improved failover capability.
Although one or more CTI Managers can be active
in a cluster, only one CTI Manager can exist on an
individual server. An application (JTAPI/TAPI)
can have simultaneous connections to multiple CTI
Managers; however, an application can only use
one connection at a time to open a device with
media termination.
